[0002] A wind turbine is a device that converts wind energy into electricity and is a major form of renewable energy technology. It uses the kinetic energy of wind to drive a generator through rotating blades, generating electricity. Wind turbines are widely used in wind farms and stand-alone power generation systems to generate clean electricity.

[0003] Existing wind turbine nacelles are usually fixed with rivets to form an integral nacelle. When replacing, the nacelle needs to be replaced and installed as a whole, making the installation and disassembly of the device more cumbersome. In addition, the air inlet opened on the outside of the nacelle is relatively small, resulting in poor internal heat dissipation, which causes components such as the generator and transmission to overheat during operation, affecting power generation efficiency and equipment life.
